DRAW-BAR PRESS.

Specification of Letters Patent.

Patented May 23, 1916.

Application filed June 16,1915. I Serial No. 34,479.

'1 '0 all whom it may concern Be it known that I, Moss Moses, a citizenof the United States, residing at Jackson, in the county of Madison andState of Tennessee, have invented certain new and useful Improvements inDraw-Bar Presses; and I I do hereby declare the following to be a full,clear, and exact description of the iiivention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention is an improved ress for use in shortening the draw barslocomotives, which become unduly lengthened as a result of the stress towhich they are subjected in pulling the trains, the object of theinvention being to provide an improved press of this character y meansof which a locomotive draw bar may be readily shortened and whichrequires the services of from two to four men in its operation while theoperation of shortening a draw bar, as heretofore practised, requiresthe services of from six to eight men.

The invention consists in the construction, combination and arran ementof devices hereinafter described an claimed.

In the accompanying drawings :-Figure 1 is a. side elevation of a drawbar press constructed in accordance with my invention. Fig. 2 is a planof the same. Fig. 3 is a vertical longitudinalsectional view of thesame. Fig. 4 is a detail elevation of the lifting hook. Fig. 5 is -adetail side elevation showing the press coupled to a by draulic powerpress for operation thereby. Fig. 6 is a similar view showing the pressconnected to an electric power press.

In the embodiment of my invention, I provide a box 1 which comprises abottom 2 and a pair of spaced side walls 3 which rise from the bottom. Ahead 4 is arranged between the walls and at one end of the box. Thewalls are provided at the opposite end, at their upper sides, with lugs5.

A matrix base 6 is arranged in the bottom of the press box andterminates at one end in the head 4. The upper side 7' of the matrixbase is shaped to correspond with the shape of one side of a drawbar andto adapt the press for use in connection with drawbars of differentforms, the matrix base is also provided in its upper side with aremovable member 8. This member is arranged in a recess 9 and bears atone end also against the head 4.

lVhen the member 8 is removed the matrix base conforms to the shape ofone form of drawbar and when the member 8 is in place in the recess 9the matrix base, together with the said member 8, conforms to anotherform of drawbar, as will be understood. A recess 10 is in the upper sideof the matrix base at the end opposite the head and the matrix base alsohas a transverse cross soctionally triangular recess 11 in which alifting cam 12 1S pivotally mounted as at 13. in the recess with oneside of the cam flush with the upper side of the matrix base asindicated in full lines in Fi 3. The cam may be turned to a verticaposition and caused to project above the matrix base in order to lift adrawbar from the box after the drawbar has been shortened, as indicatedin dotted lines in said figure.

A lever head 14 is pivotally mounted between the lugs 5 as at 15 and isconnected by links 16 to a plunger 17 which is longitudinally movable inthe guide recess 10 of the matrix base. A lever bar 18 may be detachablysecured to the lover head by placing said bar in a socket 19 with whichthe leverliead is provided. The pivot shaft 13 of the lifting cam isprovided at its ends with beads 20 having radial sockets 21 for the recetion of bars 22, one of which is indicator in dotted lines in Fig. 1 andby means of which the cam may be readily turned to lift and facilitatethe removal of a drawbar after the drawbar has been shortened.

In the operation of my improved press a drawbar is first heated andplaced in the press, on the matrix base and with one end against thehead 4, the plun er 17 having been drawn outwardly a sul'cient distance,by upturning the lever head 14. I'Vhen the draw bar has been thusarranged the lever head 14 is turned downwardly by its bar 18, thusforcing the plunger inwardly and hence shortening the draw bar betweenthe plunger and the head 4, the inner limit of movement of the plungerbeing determined by the shoulder 23 the space between said shoulder andthe head 4 corresponding with the required length of tho drawbar. Theremovable standard.

Said cam is normally arranged member 8 is provided with a recess 24 inwhich is an eye 25 for engagement by a hook 26, wherewith to lift saidmember 8 when'it is desired to remove the same.

To hold the drawbar and prevent it from buckling while being shortenedin the press suitable rods 27 are provided which may be placcd'in andextended through openings .28 in the wall 3.

When'it is desired to use my improved press in connection with hydraulicelectric power for operation thereby instead of manually, I remove thelever 14 and the links 16 and connect a coupling head 29 to the plunger17 by means of a )in 30, said coupling head having a shanlr 31 forattachment to a hydraulic cylinder or electric power apparatus as shownin Figs. 5 and (3 respectively so that the press may be operated byeither hydraulic or electric power.

Having thus described my invention, I claim 1. A drawbar press of theclass described comprising a box, having a head at one end, and a leverhead pivotally mounted at the other end, a matrix base in the bottom ofthe box, terminating at the head and provided in its upper side with aguide recess at the end opposite the head, a plunger arranged formovement in said recess and connections between the plunger and thelever head to enable the plunger to be operated by the lover head.

2. In a drawbar press a press box, ahead therein, a matrix base, aplunger, means to operate the plunger and a lifting cam arranged in arecess in the upper side of the matrix base said lifting cam having ashaft iivotally mounted in the walls of the press ox and provided at itsends with means whereby said cam may be turned.

3. In a drawbar press a press box, a head therein, a matrix base, aplunger, means to Ooptu oi this patent may be obtained for two centseach,

operate the plunger, said matrix base having a detachable member in itsupper side 'corresponding with one form of drawbar,

the recess corresponding with another form of drawbar.

4, Adrawbar press of the class described having a matrix base, a head inone end of the base, a shoulder at the other end of the base, a plunger,and means by which the plunger maybe operated, said shoulder limitingthe inward movement of the plunger.

5. A drawbar press of the class described having a matrix base, a headin one end of the base, a plunger at the other end of the base,operating means for the plunger, and means to prevent the drawbar frombuckling while being subjected to pressure by the plunger. 7

6. A drawbar press of the class described having a matrix base, sidesrising vertically frointhe base, a head located between the sides at oneend of the base, the opposite end of the base having a recess, ashoulder at the end of the recess, a plunger slidably mounted in saidrecess, a lever head pivotally mounted to and between the sides at saidother end of the base, and a link connected to the lever head andplunger, said shoulder limiting the inward movement of the plunger.

7. A drawbar press of the class described having a matrix base,stationary sides rising vertically from the base, a head located betweenthe sides at one end of the base, a plunger slidably mounted between thesides at the other end of the base, and means by which the plunger maybe operated.

In testimony whereof I afiix my signature in presence of two witnesses.

MOSE MOSES.
